The Flexural Behaviour of Tubular Steel Member Strengthened With CFRP

Carbon Fibre Reinforced Polymer (FRP) has increasingly become an attractive option for retrofitting steel structures. This paper presents the result of recent study of retrofitting three tubular steel tubes. The tubular steel tubes were cut at the center to represent the loss of steel volume due to corrosion. It was then wrapped with two and four layers of CFRP respectively. The specimens were then tested in a four point loading system and compared to the control specimen. The results show an improved load carrying capacity of the strengthened tubular steel tubes with insignificant reduction of ductility.

Chapter 193Strict Orders for Observance of Obligatory Salat

Hadith 1076Ibn `Umar (May Allah be pleased with them) reported: The Messenger of Allah(PBUH) said, "I have been commanded to fight against the people till they testify La ilaha illAllah (There is no true god except Allah) and that Muhammad (PBUH) is His slave and Messenger, and to establish As-Salat (Iqamat-as-Salat), and to pay Zakat; and if they do this, then their blood and property are secured except by the rights of Islam, and their accountability is left to Allah."[Al-Bukhari and Muslim].
